Three Scottish Cup ties have been postponed due to waterlogged pitches.
Stirling Albion v Cumbernauld Colts has been rearranged for Tuesday, while Dumbarton v Alloa Athletic has been rescheduled for 8 December.
And the tie between Wick Academy and Linlithgow Rose, the only junior side in the competition, has also been called off.
Thirteen other ties are scheduled for Saturday, with Championship and League One sides entering the competition.
League Two, the Highland and Lowland Leagues and the East of Scotland League are also represented.
All Premiership sides and Hibernian, Queen of the South, Rangers and St Mirren enter at the fourth-round stage.
